Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSART042SCG3R9CWRA01 is determined by strict equivalence across the following parameters:

Electrical Specifications:

• Capacitance value: 3.9 pF
• Tolerance: ±0.25 pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Specifications:

• Package type: 01005 (0402 Metric)
• Mounting: Surface Mount, MLCC
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)

Compliance & Environmental:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all electrical parameters, maintain identical package dimensions, and satisfy the same compliance requirements. The CC0100CRNPO8BN3R9 from YAGEO meets these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CC0100CRNPO8BN3R9 (YAGEO) is a direct parametric equivalent to the MSART042SCG3R9CWRA01 (Taiyo Yuden). Both components are Active product status and carry identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability, supply chain requirements, and procurement preferences, as both satisfy all functional and environmental requirements for general purpose ceramic capacitor applications.

Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the CC0100CRNPO8BN3R9 be used as a direct replacement for the MSART042SCG3R9CWRA01?

A: Yes. Both components share identical electrical specifications (3.9 pF, ±0.25 pF tolerance, 25V rating, C0G/NP0 temperature coefficient), mechanical dimensions (01005/0402 Metric package), and compliance certifications (ROHS3, MSL 1). Direct substitution is supported without circuit modification.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both the MSART042SCG3R9CWRA01 and CC0100CRNPO8BN3R9 operate across the identical temperature range of -55°C to 125°C.

Q: What does the 01005 (0402 Metric) package designation mean?

A: The 01005 designation refers to the imperial size code, while 0402 Metric is the metric equivalent. Both describe the same physical package: 0.016" length by 0.008" width (0.40mm x 0.20mm), with maximum thickness of 0.009" (0.22mm). This is one of the smallest surface mount capacitor packages.

Q: Do these capacitors require special handling during assembly?

A: Both components carry MSL Level 1 (Unlimited) moisture sensitivity rating. This classification indicates no moisture-related storage or handling restrictions are required prior to soldering.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G (IEC standard) and NP0 (EIA standard) designations describe the same temperature coefficient characteristic: negligible capacitance change across the operating temperature range. This stability is critical for precision analog circuits and frequency-dependent applications.

Q: Can these 3.9 pF capacitors be used interchangeably with other capacitance values?

A: No. The 3.9 pF value is specific to circuit design requirements. Substitution is limited to parts with identical 3.9 pF capacitance and ±0.25 pF tolerance specifications.
